The website was set up after the Internet Matters campaign found almost three-quarters (74%) of the 1,500 parents they spoke to said they wanted to know more about how to protect their children online.

The campaign, which is funded by the four internet service providers but operates independently, aims to remove uncertainty and provide parents with access to simple, current and practical advice.

Singer Sophie Ellis Bexter and her mother Janet will push the button to set the Internet Matters portal live at the launch event at the Museum of Childhood in Bethnal Green, London, later today.
